frontend-design

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

The user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.

Design Thinking

Before coding, understand the context and commit to a BOLD aesthetic direction:

• Purpose: What problem does this interface solve? Who uses it?
• Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
• Constraints: Technical requirements (framework, performance, accessibility).
• Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.

Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is:

• Production-grade and functional
• Visually striking and memorable
• Cohesive with a clear aesthetic point-of-view
• Meticulously refined in every detail

Frontend Aesthetics Guidelines

Focus on:

• Typography: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.
• Color & Theme: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.
• Motion: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available (Use anime.js for animations: ./references/animejs.md). Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.
• Spatial Composition: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.
• Backgrounds & Visual Details: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.

NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.

Interpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.

IMPORTANT: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.

Remember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.

Subagent UI Research Integration (The Awwwards/ThreeUI Flow)

Before committing to an aesthetic direction or writing code, YOU MUST delegate UI research to a subagent to extract high-quality, real-world design patterns from top-tier inspiration galleries.

1. Invoke the Subagent: Call the invoke_subagent tool with a research type agent. Prompt for Subagent: "Vào trang threeui.com, awwwards.com, hoặc godly.website. BẮT BUỘC KHÔNG lấy mẫu ngẫu nhiên ở trang chủ. Bạn phải trích xuất bối cảnh hiện tại (ví dụ: 'E-commerce Checkout', 'SaaS Analytics Dashboard', 'Healthcare Portal') và SỬ DỤNG THANH TÌM KIẾM (Search) của trang web để tìm ĐÚNG mẫu UI khớp 100% với bối cảnh. Sau khi lọc kết quả, hãy dùng công cụ chụp ảnh và ai-multimodal để phân tích sâu về: 1) Bảng màu (Hex codes), 2) Typography (Tên font, size, weight), 3) Cấu trúc Layout Grid, 4) Micro-interactions. Viết báo cáo chi tiết kèm Tailwind config để Main Agent implement."

2. Subagent Execution (Playwright + Multimodal): The subagent will use playwright to scrape the galleries or capture screenshots, and use the ai-multimodal skill with Gemini Vision to synthesize a highly accurate, beautiful UI specification.

3. Incorporate Findings: Once the subagent returns the DESIGN_GUIDELINE.md or the synthesis report, you must strictly follow its exact color hex codes, spacing variables, and layout structures to implement the frontend. Do not invent generic AI designs; ground your implementation in the subagent's researched evidence.
